Question

Is f(x)=|x| an even function, an odd function, or neither? Explain.

Answer 1

wow is it ever even

Answer 2

\(f(x)=|x|\), \(f(-x)=|-x|=|x|=f(x)\) so since \(f(x)=f(-x)\) it is even for sure

Answer 3

for example, \(f(-3)=3\) and also \(f(3)=3\) function cannot tell the difference between a positive and a negative number

Answer 4

Got it, thanks :)
